Hi everyone,
I'm setting up my first reef tank and got a Varios-4 pump for a 40B and a 29G sump. Inspired by the 52 weeks of reefing's BRS160, I want to have a manifold with 3 ports. My tank is plumbed for 2x3/4 returns.
The Varios-4's output can be 1" slip or 3/4" barb. My initial thinking was to use 3/4 ID silicone tubing to 3/4" PVC for everything. I doubt 3/4" would limit any flow I want on a 40B, even with 3 manifolds for reactors.
Then after reading a bit more and remembering some highschool physics, I realize that for the same pressure, using 1" would give me more flow and thought about using 1" from the pump to the manifold, then use 2 reducing tees to have my 2x3/4" return to the tank. Would this be a better approach? If so, what is the recommended method to attach 1" ID silicone tubing between the pump and the 1" PVC for the system?
